6 Observations
Higher Level of Difficulty
Observed Data
Model: y = f(x;beta) + e = beta(1)(1 - exp[-beta(2)x])

These data are described in detail in Box, Hunter and Hunter (1978). The response variable is biochemical oxygen demand (BOD) in mg/l, and the predictor variable is incubation time in days.
